Abstract:The research was conducted on preparation of nickel-coated tungsten composite powder by hydrazine reduction in aqueous solution and the effect of processing conditions on the deposition of nickel upon tungsten was investigated. The results indicated that under proper processing conditions uniform deposition layer of nickel upon tungsten powder can be obtained from the nickel chloride solution which contains suspended fine tungsten particles, and the hydrazine reduction is an effective, simple and low cost method for nickel-coated tungsten composite powder preparation.
